To all 'whom t may concern.'- v

Be it known that I, Gmncn ALBERT LYON, a citizen of the United States, and resident of Philadelphia, county of Philadelphia, State of Pennsylvania, .have made a certain new and useful Invention Relating to Rear Attaching Devices, of which the following is a specification, taken in connection with the accompanying drawing.

This invention relates especiallyy to attaching devices for attaching resilient buffers or bumpers to the rear of Ford or similar automobiles 'and comprises special attaching plates adapted to be clamped or bolted beneath the rear end of the frame channels as by U-bolts extending around the channels while Vflanges or locking lugs or projections on the plates promote the alignment and gripping engagement of the plates with the frame channels and adjacent spring angle iron or other supporting member. These attaching plates preferably diverge outward as they extend rearward from the automobile frame and are provided with stiifening ribs or flanges to give them increased s'tiiiness against vertical bending forces whilev adjacent their free rear ends they are preferably provided with a vertical clamping face which may have bolt holes to assist in bolting or clamping the attaching arms or portions of the buiier thereto.

In the accompanying drawing which shows in a somewhat diagrammatic Way an illustrative embodiment of this invention:

Fig. 1 is a top view.

F ig. 2 is a vertical sectional view taken substantially along the line 2-2 of Fig. 1.

Fig. 3 is an enlarged top view of the attaching plate separated from the other parts, and

Fig. 4 is a transverse sectional view theretaken substantially along the line 4 4 of The attaching plates used in this device are preferably formed of spring steel plate or strip of an inch thick more or less and preferably hardened and 'tempered after they have been cut and bent to shape in suitable dies or otherwise.l As shown in Figs. l and 3, thattaching plate 5 may have a relatively wideflat clamping surface on its upper faceadjacent one end where it is adapted to be clamped or secured to the frame members and this part of the plate may be stiened and strengthened as by forming one or more depressed stiiening above the axle casing .1. the retaining flanges 10 may be formed on lwith the lock washers 7 and nuts 8. it is desirable to form one orl more retaining locking lugs or flanges on this part of the attaching plate in such position as to engage or cooperate with the frame channel or transverse spring angle iron 3 'to which the spring 2 may be secured substantially For this purpose these plates and preferably provided with locking ends 22 which may extend under the spring angle iron to substantially engage its rear flange when the attaching plates are in their adjusted position shown in Fig. 1. It is of course understood that each of these attaching plates may be inserted laterally under the rear end of the frame channel so as to bring these locking lugs or ilanges into proper position before the U-bolts or other clamping devices are put inplace and tightened so as to hold the plates securely and rigidly in their rearwardly extending position with their upper surfaces at sublstantially the same level with the lower edges of their frame channels.

lihe inner adjacent edges of'these attaching plates 5. which preferably diverge outwardly as they extend backward from the automobile frame may be formed with depending stiening ilanges such as 24 which may overlap the stiii'ening rib 14 and increase in vertical height as they extend rearward as is shown in Fig. 2. This Harige at the rear of the attaching plate is bent into substantially parallel position so as to fom a vertical clamping face 12 which may be provided with holes or slots such as 13 through which the clamping bolts 15 may extend 'to rigidly secure thereto the bumperv attaching members or strip ends 17 of the buffer when the nuts 16 are tightened. These nuts preferably draw the attaching ends of the bumper up against the npr aligning face 23 of the attaching plate so as to give amore rigid connection at this point. The bufer ymay be of any suitable or desired construction referably comprising resilient strips attac ing arms or members mtb s3 .inseam such as 17 which may in some casesbe in- Y tegral with the end -loops '18 and inwardly extending impact receivlng members 19, 20. ln the case of a Lyon type buffer these impact` receiving members may overlap and be secured in adjusted position as by the enclosing clamping devices 21 of the "usual form. 'After these attaching plates have been connected to the automobile frame adjacent the rear axle casing 1 the buffer strips or members may be bolted to these attaching plates either before or after the strips have been connected together and in some cases the buffer strips may be forced apart 'so as to resiliently force the attaching plates outward at their projecting rear ends which tends to increase the gripping engagement of the U-bolts with the automobile frame members.

"the fw:

rllhis invention has been described in connection with a number of embodiments, forms, proportions, parts, arrangements, maf terials, methods of connection and use, to the' details of which disclosure the invention is not of course to be limited since what isclaimed as new and what is desired to be secured by Letters Patent is set forth 1n the appended claims.

l. ln automobile buffer devices, a spring.

strip louder comprising attaching members, connected end loops and overlapping impact receivin members adjustably connected in reenforcing position, and attaching plates of tempered sheet steel each having adjacent one end a substantially tlat upper clamping surface adapted to t beneath the rear ends of the frame channels and spring angle iron of a Ford automobile and formed with retaining danges to engage said frame members and align the plate oWith respect thereto, ll-bolts extending around said frame members and assingl throu h holes in said attaching p ates to secure y connect the plates thereto, stidening bent portions formed on said plates and comprisinga depressed stiffening rib and edge stiiiening ange forming a substantially vertical clamping face at a end of the plate adjacent the upper aligning face thereof and bolts to connect the attaching members of the bilder to said verticalv clampin faces.

2. ln automobi e buffer devices, a spring strip buder comprising attaching members and impact receivi members, and attach'-` in pl each having adjacent one end a 'sustantially dat upper clamping surface adapted to nt beneath the rear ends of the fra channels and spring angle iron of a Ford automobile, llll-bolts extending around said frame members and passing through 'holes in said attaching plates to securely connect the plates thereto, stidening bent portions formed on said plates and comprising adep'rsed stidening rib and edt stienin 'ange forming a substantiay. vertice clamping face at the free end-ofthe plate ad'acent the upper aligning face thereof and bo ts'to connect the attaching members of.

the bu'er to said vertical clamping faces.

3. In 'automobile' louder devices, a spring strip bud'er comprising attaching members and impactreceiving members, and attaching plates 'each having adjacent one end a substantially Hat upper clampin surface secured beneath the rear ends o the frame channels and s ring angle iron of a Ford automobile, sti ening bent portions formed on said plates perpendicular to said clamping surface and comprising edge sti'ening.

flanges forming substantially vertical clamping faces at the free end of the plates to which the attaching membersv of the bufer are secured. v

4:. In automobile buder attaching devices, forged steel attaching plates having adjacent one end substant1ally Hat upper clamping surfaces adapted to fit beneath the rear ends of the frame channels of a Ford auto mobile and formed with aligning retaining members adapted to engage said frame members and align the plate with respect thereto, U-bolts .extending around said frame members and passing through holes in said attaching plates to securely8 connect them to vthe frame members said attaching plates having`outwardly diverging gradually narrowing rear ends and having stideni @i bent portions comprising edge stilenin anges forming substantially vertical c amping faces at thefree' rear ends of the plates adja- -cent the upper aligning face thereof to lid@ which the attaching members of the bilder may be connected.
